Multiconductor for industrial environments

The AKAPP 7-Pole conductor bar system is a proven solution for the reliable power supply of moving equipment in a wide range of industrial environments. Designed for demanding applications where robustness, safety and long service life are essential, the system performs consistently, even under harsh operating conditions.

The Multiconductor system is based on the ‘AKAPP LongLife’ technology, closed conductor rail design with continuous copper conductors, fully integrated within a durable insulating housing. Offers excellent protection against dust, moisture and mechanical impact, making it highly suitable for industrial sectors such as overhead cranes, agriculture and heavy-duty production environments.

A key feature of the system is the use of continuous, joint-free copper conductors, ensuring uninterrupted power transmission, minimal voltage loss and reduced wear. The internal current collectors, running inside the protected rail housing, guarantee stable contact conditions and contribute to a long lifetime with low maintenance requirements.

Thanks to its modular design and wide range of options, the Multiconductor system is the go-to ‘Solve-All’ solution, including long travel distances, curves and switches. This makes it a versatile choice for a broad range of industrial applications.

LEARN ABOUT

Continuous Copper Technology with Akapp LongLife

AKAPP LongLife conductor bar systems use continuous copper conductors to eliminate mechanical joints and minimise transition resistance. The smooth, uninterrupted contact surface reduces heat build-up and wear on collector trolleys, ensuring reliable power transmission, longer carbon brush life and lower maintenance requirements.

Overhead cranes, gantry cranes

Overhead cranes and gantry cranes are most used in manufacturing sites, shipping ports, rail yards and construction sites. These systems are typically installed on track systems and equipped with Akapp Multiconductor systems for power supply, enabling cranes to travel along fixed rails. They are used for lifting and transporting heavy loads such as containers, steel components and large industrial equipment within a defined working area.

Agriculture and horticulture systems (greenhouses, moving installations)

Agriculture and horticulture systems, such as cattle feeding systems and modern greenhouses, rely on integrated internal transport and moving installations to support efficient operations. These systems are equipped with Akapp Multiconductor systems for power supply, due to their durable insulating housing, Curved sections options, protection against moisture and humidity, making them suitable for reliable operation in demanding conditions.

Automatic precast concrete plants

Automated precast concrete plants are used for the production of prefabricated concrete elements such as walls, floors and structural components. These facilities rely on automated transport systems and production lines operating under heavy loads and dusty conditions. These systems are typically equipped with Akapp Multiconductor (and PowerPOZ) conductor rail systems for power supply (and positioning), due to their closed and robust design with integrated conductors, providing protection against dust and mechanical impact for reliable operation.

Building façade maintenance systems (BMU installations)

Building façade maintenance systems (BMU installations) are used for the inspection, cleaning and maintenance of building façades, typically on high-rise structures. These systems operate on tracks along rooftops or façades and involve moving platforms to safely access different areas of a building.

The power supply of these maintenance units needs to be protected against weather conditions such as moisture, wind and dirt. The Akapp Multiconductor conductor bar system features a closed design with flexible sealing strips, making it suitable for reliable operation in all outdoor conditions.
